Polygon's Lisovo Upgrade went live on March 4, 2026, introducing several infrastructure improvements focused on AI agent transactions and payment systems.
Key Features:
- $1M gas subsidy program for agent transactions, offering rebates on Polygon x402 facilitator transactions
- Dynamic fee adjustments without requiring hard forks
- Enhanced security standards aligned with latest Ethereum protocols
- Improved wallet compatibility and smart contract support
The upgrade aims to reduce operational costs for developers building autonomous agent systems. Agents can now execute buy, sell, and transaction operations with subsidized gas fees.
Polygon's Trails infrastructure supports natural language commands for cross-chain operations, enabling agents to swap tokens and move assets between networks without custom code.
